But how about the presumption--the legal presumption, arising from such lapse of time as that the memory of man runneth not to the contrary--the presumption springing from tradition and common report--that William Shakespeare composed the Shakespearean plays? It is, of course, understood that one presump{016}tion is as good as another until it is disturbed. It is never safe to underrate an existing presumption; as long as it stands at all, it stands as conclusive; once overthrown, however, it is as if it had never existed. A presumption three hundred years old may be a strong one to overthrow. But if its age is all there is of it--if it be only strong in years--it can yet be toppled over. Once overthrown, it is no more venerable because it is three hundred years old than if it were only three. An egg-shell will toss upon the crest of an angry surf, and, for very frailty, outride breakers when the mightiest ship man ever framed could not survive an instant. But it is only an egg-shell, for all that, and a touch of the finger will crush and destroy it. And so, formidable as it was in age, the presumption as to William Shakespeare's authorship of the great dramas which for three hundred years had gone by his name, had only to be touched by the thumb and finger of common sense to crackle and shrivel like the egg that sat on the wall in the Kindergarten rhyme, which all the king's army and all the king's men could not set up again, once it had tumbled over. But as the world advanced and culture increased, why did not the question arise before? Simply because the times were not ripe for it. This is the age and generation for the explosion of myths, and, as one after another of them falls to pieces and disappears, who does not wonder that they have not fallen sooner? For how many years has the myth of William Tell been cherished as history! And yet there is no element of absolute impossibility or even of improbability--much less of miracle--in the story of an archer with a sure eye and a steady aim. Or, in the case of physical {017}myths--which only required an exploration by physical sense for their explosion--the maps of two centuries or so ago represented all inaccessible seas as swarming with krakens and ship-devouring reptiles. And it is not twenty years since children were taught in their geographies that upon the coast of Norway there was a whirlpool which sucked down ships prow foremost. And here, in our midst, a cannon-shot from where we sit and write these lines, there was believed to be and exist a Hell Gate which was a very portal of death and slaughter to hapless mariners. But there are no krakens, and not much of a Maelstrom; and, for twenty years before General Newton blew up a few rocks at Hell Gate, people had laughed at the myth of its ferocity. And again: nothing is easier than to invent a story so utterly unimportant and immaterial that it will be taken for granted, without
